Rapid weight loss

Ive been losing steadily without ever going over my calorie goal and i feel really good. The past few days i had my own graduation party and was at a few of my friends parties too, i had some yummy stuff but i definitely didnt over eat anything. During those days i lost the most weight i have in half a week, i lost about the same amount a week and a half would do and im almost at my goal so i guess it should be harder? My body doesnt feel weird at all but i wanna make sure im not doing anything wrong.
